Abstract
Data transformation is a crucial step in data integration. While some transformations, such as liters to gallons, can be easily performed by applying a formula or a program on the input values, others, such as zip code to city, require sifting through a repository containing explicit value map-pings. There are already powerful systems that provide for-mulae and algorithms for transformations. However, the au-tomated identification of reference datasets to support value mapping remains largely unresolved. The Web is home to millions of tables with many containing explicit value map-pings. This is in addition to value mappings hidden be-hind Web forms. In this paper, we present DataXFormer, a transformation engine that leverages Web tables and Web forms to perform transformation tasks. In particular, we describe an inductive, filter-refine approach for identifying explicit transformations in a corpus of Web tables and an approach to dynamically retrieve and wrap Web forms. Ex-periments show that the combination of both resource types covers more than 80 % of transformation queries formulated by real-world users. 1.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
